Title: Improvements in the thermal cracking of liquid hydrocarbons
IPC: C01B3/34
Filed: 1957-04-16
Abstract: <PICT:0801708/IV (b)/1> A process for the thermal cracking of liquid hydrocarbons in the liquid phase comprises allowing a flame to burn beneath the surface of the liquid by supplying to a burner below the surface, oxygen or a gas containing molecular oxygen and a fuel, the oxygen being present in a smaller quantity stoichiometrically than the combustion of the fuel to water and carbon dioxide.  In an example, a diesel oil of boiling range 200-325 DEG  C. was cracked in an iron container 1 which is surrounded by a cooling jacket 6 through which water flows.  A gauge 7 enables the oil level height to be controlled.  A vertically arranged burner dips into the oil from the top and consists of a mixing chamber 4, supply pipes for oxygen 2, and a gaseous fuel 3, such as methane, and a burner pipe 5.  The oil is maintained at 110 DEG  C.  The cracked gases are led through a pipe 8 to an indirect cooler 9 in which they are cooled to 20 DEG  C. Water settles out in tank 10 and is withdrawn through valve 12, the oil returning to the plant via a pipe 11.  Oil contaminated with soot is withdrawn through a pipe 14, filtered and returned through a pipe 15.  The gaseous product consists chiefly of carbon monoxide, carbon dioxide, hydrogen and acetylene together with some methane. Specification 795,688 is referred

Patent GB-125133-A (GB)
IPC: F02B41/06
Abstract: 125,133. Ricardo, H. R. June 6, 1916. Four-stroke-cycle engines; charge, cooling.-In an engine in which both the compression and the expansion of the explosive charges are carried out in two stages, part of the products of combustion are cooled and are then used to dilute the explosive charges. The invention is described in connexion with a compound engine of the kind described in Specification 17882/15. When the low-pressure piston D has performed part of its stroke, it uncovers one or more ports B<1> and allows some of the burnt gases to pass through a cooler K<2> comprising tubes K surrounded by water. After passing a valve L, the partly cooled gases enter a second cooler G, into which compressed air or weak mixture is forced by the piston D. The gases from the cooler G enter the high-pressure cylinders A, A<1> through valves J, J'. In a modification, the ports B' are omitted, the products of combustion being admitted to the cooler K<2> by means of a valve arranged in the head of the low-pressure cylinder. Instead of passing the gases from the cooler K<2> into the cooler G, they may be passed into a second cooler which is independent of the cooler G and is connected to additional admission valves arranged in the heads of the cylinders A, A'.

Title: Improvements in and relating to the desulphurisation of hydrocarbons containing sulphur compounds
IPC: C10G49/00
Filed: 1950-05-19
Abstract: Hydrocarbons containing sulphur compounds are desulphurized by treatment with a gas containing 20 to 60 per cent by volume of hydrogen while they are passed in a liquid film at a temperature above 200 DEG C and pressure above 10 atmospheres over a stationary fragmentary catalyst comprising an oxygen-or sulphur-containing compound of a metal of Group VI of the Periodic System and an oxygen- or sulphur-containing compound of a metal of Group VIII of the Periodic System.  The feed gas may contain nitrogen and hydrocarbons, and may suitably be gases produced by catalytic cracking, with or without additional hydrogen, or by re-forming of normally liquid or gas hydrocarbons or by the dry distillation of hydrocarbonaceous substances such as gas coal.  The gases leaving the reaction zone, which have a comparatively low hydrogen content, may be discharged from the system The amount of gas leaving the system, measured at normal temperature and pressure after removal of hydrogen sulphide, should be less than 500 litres per kilogramme of hydrocarbons treated.  Any carbon monoxide and unsaturated hydrocarbons in the gas should preferably be eliminated.  Cobalt and molybdenum oxides or sulphides, or a cobalt salt of molybdic acid or molybdenum sulpho-acid on aluminium oxide as a carrier form suitable catalysts. The results of tests describing the desulphurization of a gas oil (boiling range 260-350 DEG C) containing 1.33 per cent sulphur using a feed gas of pure hydrogen, 40 per cent hydrogen and 60 per cent methane, 40 per cent hydrogen and 60 per cent nitrogen and 50 per cent hydrogen and 50 per cent carbon monoxide are reported.

A dictating machine employing a short wide belt record includes a stationary frame 68, Fig. 2, supporting a drive mandrel 70, an idler mandrel 76 mounted on the opposite side of said frame and movable to and from the mandrel 70 on spring-loaded rods 80, 82 under the influence of cam-lever 100 acting against a bar 88 mounted on the ends of rods 80, 82, a telescopic track 60 mounted on top of said frame between said mandrels and carrying a guide plate 62 for facilitating loading of a record band into position on the said mandrels, springs 120, 122 acting outwardly on the track 60 with greater tension than the outward spring loading of the mandrel 76, a cam 172 on frame 68 unlatching cam lever 100 and causing the bar 88 and mandrel 76 to be released outwardly when track 60 and guide plate 62 is moved inwardly against springs 120, 122 to a position latched by a member 178 which engages a pin 176 on track 60. The record band is inserted between track 60 and a guide plate 62 while in retracted position and guide members 64, 66 guide the record band through the window 16 and over the mandrels 70, 76, which have a greater diameter than the combined thickness of frame 68 and track 60. Inward movement of guide plate 62 causes levers 144, 164 to be raised by a cam wall 162, Fig. 5, so that turned up ends 140, 142, respectively, on levers 144, 164 engage the outer edge of the record band and draw it into position against a flange 169 on the idler mandrel 76, lost motion in the latch member 178 causing the tongues 140, 142 to move clear of the record band after latching of member 178. The record band is ejected by the operation of a button 50, Fig. 1, which rotates a rod 192, Fig. 6, and through a linkage 208, 210 trips the latch member 178. The recording head 290 and playback head 256 are pivotally mounted on a carriage slidable on the rods 192 and 194, either by the leadscrew 196 driven through gearing from the shaft 71 of the mandrel 70, or manually in neutral position (i.e. with leadscrew 196 inoperative and heads 256, 290 disengaged from the record) by means of a control member 20. The control arm 20 is mounted at the end of a control shaft 232 on the transducer carriage and is rotatable to left or right by means of press-buttons 22, 24 geared thereto for lowering head 290 or 256, respectively, according to whether a recording or playback operation is required. At the same time, a cam 322 on the shaft 232, Fig. 11, causes a worm 310 to be locked against rotation so that the lead screw 196 causes the traverse of the transducer carriage. When control shaft 232 is rotated to either the record or playback positions, a cam 252, Fig. 8, enters a quadrant-shaped groove in rod 192 and locks it so that the latch member 178 cannot be tripped to eject a record band. Specification 553,378 is referred to.

Title: Improvements in brakes
IPC: F16D65/14
Filed: 1944-07-06
Abstract: 588,035. Brakes. NEALE, F. July 6, 1944, No. 12884. [Class 103 (i)] A unit for interposition between a brake shoe and a fixed member and/or in the brake shoe applying means to effect automatic adjustment to compensate for wear, comprises a plunger carried by a first member and urged in one direction by a spring to abut on a second member, movement of the plunger relatively to the first member in the opposite direction being prevented by the resilient engagement of ratchet segments with annular ratchet teeth formed on the plunger. As shown, shoes 3 pivoted at their lower ends are operated by a pair of pistons 12 through levers 13 pivoted on the shoe carrier 5. The pistons may be operated either by pressure fluid or by a cam 7 connected by an Oldham coupling 10 to an operating shaft 9. A bush 8 on which the cam is rotatable has a rectangular slot engaged by a fixed pin 11 so that the cam can move laterally to equalize the pressure applied to the shoes. An automatically adjustable stop device for determining the clearance between the shoe and drum in release comprises a plunger 55 slidable in a housing 54 secured to the shoe and prevented from movement towards the drum by ratchet segments 57 held in engagement with annular ratchet teeth formed on the plunger by a coil spring 58. An auxiliary plunger 21 slidable in the plunger 55 abuts on a fixed stop 30 and normally is held in the depressed position shown against the action of a spring 22 by the brake shoe release spring 6. A similar unit comprising the plunger 15 and housing 14 but without an auxiliary plunger is provided between the shoe 3 and lever 13. When the shoe is applied by the piston 12 acting through the lever 13 and plunger 15, the plunger 21 moves outwards relatively to the plunger 55 until it engages the cap 21. This movement corresponds to the normal clearance between the shoe and the drum and if due to wear of the shoe lining, this movement is exceeded, the plunger 55 is moved outwards relatively to the shoe by the spring 56 so as'to take up one or more ratchet teeth. In releasing the shoe returns until the plug 21 is again fully depressed so that the clearance of the shoe from the drum is maintained substantially constant. Also as the piston 12 returns to its original position, the plunger 15 is moved outwards relatively to the shoe by the spring 16 to an extent corresponding to the advanced position of the shoe as determined by the adjustment of the stop device. Specification 588,036 is referred to in the Provisional Specification.
